The Online Policy Group (affiliated with the EFF) is looking to build a free, open alternative to YahooGroups, essentially web-based interface to managing and participating in mailing lists, potentially with a file manager, and polls as well. When we talked about the project, I was sure I would find software that already fit our requirement spec. In particular I expected that mature frameworks like ACS or Zope would be sure to have a product that provided this. So far though I've drawn a blank. However Zope is still pretty new to me, so I might be missing some obvious solutions that already exist. Has anyone built an eGroups clone for Zope? Or integrated existing products to provide similiar functionality? -or- Can someone reccomend the best course to go about building such a beast? Obviously Zope already can handle user management - creation, authentication, etc... And I've seen products for polls, and bulletin board systems. But is there some existing tools that either provide a standard majordomo/mailman style mailing list, or integrate with one? Advice would be greatly appreciated. Thanks kellan
